The frame of the device comprises a pl'u yrality ouprights or rods which have their lower ends inserted through abottom timber or sill v9,which, in turn, supported V,upon

TheseuprightsV are'preferably; three in numberan'd ineludea; stout rodfll located at oneVY end of the sill anda Velements 10, resting in a 'recess below the g. ,ground-line AG`L as Vshown 1n igure l of pair' oi' laterally'spaced krodsl2,zof slightly smaller diameter thanrod l1, located at 'the other end, Eas maybe 4 seen in iguref'. fTheSe rods mustheef-*suchstrength as to easilyVV withstand the' strainY of thev compressoperation. At their outer ends, the rods aire connected by @stationary platen or head rblock 13 which, ltogether with the compressor elements carried thereby, constitutes the up per die. The 'ends' of the rods extend through and-beyond both the ysill 94ar'1dthe.AA

Arranged for. movement between the upper compressor 13' and the lower .or movable compressor 2li, is the containing platen,

means for the cotton to be 'compressed. This container comprises boxesrorreceptacles 27 into which the cotton is `to be deposited, and these Yboxes may be of the usual and ordinary construction common to in upper part by encompassing bands orbraces i 2B. As the greatest pressure is exerted-on the cotton when confined within the upper part of the'box lor cotton container, these braces serve to reinforce the box at the most necessary point andfenable' it to successfully vwithstand the pressure ofl the compressor.

Figure 1.

rEhe boxes are tubular, being opened ateach end and `relatively connected by side-bare 2929, embracingthe boxes on opposite sides and adjacent the bottom and inten mediate portions, ais shown to advantage in The uppermost bars are relatively connected, inwardly of the cotton boxes, by means ofL a transverse strip 30,

having a 'central opening through which rod V11 passes, collars 31 being fixed to the rod above and below 'the strip to provide a bearing therefor. 'A similar connection is provided for the'lower set of side bars. YRod 11, therefore, provides an axis about which the cotton container revolves inY a circular e path, as indicated ink Figure 3 of the draw- ',ings; it'being noted that eachrblocl passes between upri'ghts 11 and 12 Vonce vin every revolution. Y .iWhcn the container is in the position indicated inligure 3, one ofthe boxes,rit will be noted, is positioned with its open Vend `in direct line with the upper and lower compressors,- and'since the lower compressor 24 is slightly less in size' than the cross area of the aligning'l box, it is obvious'that the-latter is freely Vmovable through Vthe box, as indicated in Figure t.

Mounted upon the top face of the vupper 82, iiofidlyconnected to the block and providing a support for one end of a long beam or arm 83, which projects laterally beyond one end of the pressframe, to provide means upon which any suitable packer mechanism may be mounted, A brace Sllpr'ovided upon one end of the block 13 and connected 'to the overhanging beam lprovides an auxilf iary support for the latter andstrengthens it. This beam extends over 'the yrevoluble cotton container, and enables the packer mechanism, which is not shown, to be properly mounted andpositioned for packing the cottonin .the box of the containerwhich is bloclr 1 3 is a group. of supportingelements disposed exteriorly fof the frame, while the cotton in the other box isbeing compressed, ln the practical operation and adoption of the invention, the frame is to be prefer-v ably located in proximity toa cotton gin, y

so as to compress the cotton as it is ginned, the compression being` lto such'A 'a density as to condition the cotton ready for the' market without requiring Athe balefto be re-pressed. As the cotton is giniiedit ispacked Vby any suitable means, into one of the boxes ofthe cotton container which is overhung by the packer mounting 33; anysuitable packing mechanism being V*employed for packing the the same into position between theicompressors V13 and 24C, between which it 'is ultimately compressed to the required kdensity. TheV actuationV of the plunger may steam, orotherwise, the fluidbeing forced into the cylinder throughropening ,21' and acting upon4 the plunger whichisra-ised thereby so thatrplaten 2a is-movedin the direction of platen y13,A the cotton between' being thus compressedinto the shape defined by the concaved surfaces of elements- 2 5. lt will be seen that Jthe concave surfaces of the elements 25 exercise a peculiar function in that theyy start thecompression vat the;

edges of the bale` so that the material of such bale is crowded in toward the center as thebale is formed. Gonsequently the bale formed differs not only in shape but also in the. internal structure and density ar .120

vrangement ofr thebale, being` compressed in c such manner that no rebalingisnecessary. Much of; the pressure of the-operation is borne by elements 25 themselves,V which practically encircle thebale andthus relieve vg Athe Side walls of the' cotto-n container. The

shape ofthe bale, when completed-and' out Vofthe press, is almost jround or elliptical,

and' is therefore, adapted to'be Vmore conveniently handled than thel square shaped cotton in the container, prior to 'swinging 21,00;

bale. The press is designed to be also Aused and operated by any large ginner, andwill prevent to some degree, the accumulation pedient and fallwithin the scope of the of so much cotton at compresses, whichV so frequently proves a burden. Y
